i. Stercorarius pomarinus. Pomarine Jaeger,{and 2. Stercorarius 
parasiticus. Parasitic Jaeger)— These species, taken together, were 
among the most common seen on the trip. From three to ten individuals 
could be seen any day at the fishing grounds, flying around among the 
Terns, chasing them about and compelling them to drop their fish. Every 
day on the ‘slack’ of the tides, when the bluefish bait seemed to be more 
abundant than at other times, the Terns would go over in crowds from 
Great Gull to the ‘Race’ to fish, and though no Jaegers could be seen in 
the air before the arrival of the Terns, no sooner would the latter begin 
to fish than the Jaegers would gather around to pursue their regular busi¬ 
ness of robbery. As soon as a Jaeger would spy a Tern with a fish in its 
bill off he would start in pursuit, and dodge and dart as the Tern would, 
the Jaeger was always right in its track, pressing it closer and closer, 
until, despairing of ever eluding its pursuer, the poor Tern would drop 
the fish, which would be caught by the Jaeger before it reached the water. 
Although the Terns were swift and graceful flyers they were no match for 
their larger and more powerful enemies, who, when not engaged in pursu¬ 
ing the Terns, might sometimes be seen resting singly or in flocks of four 
or five on the surface of the water. 
Chas. B. Field informed me that the Jaegers, or ‘Hawks’, arrived 
about the same time as the bluefish, and stayed as long as the bluefish 
were there, but that he never saw them in the winter. 
When I arrived at Little Gull both Jaegers and Shearwaters were very 
tame indeed, not seeming to pay the least attention to us when we went 
out among them after bluefish ; in fact, I was told that a bird of one of 
these species had, a short time before, been knocked down with an oar. 
But after we had shot three or four of them, they seemed to grow wilder. 
The Jaegers while on the wing keep the tail widely spread, in the shape 
of a fan, the long feathers, when the birds have them, being kept close 
together. 
The Jaegers and Shearwaters could be easily distinguished from each 
other by their generally different appearance.
